Anthony Leiserowitz, PhD


Anthony Leiserowitz is an expert on American and international public opinion on global warming, including public perception of climate change risks, support and opposition for climate policies, and willingness to make individual behavioral change. His research investigates the psychological, cultural, political, and geographic factors that drive public environmental perception and behavior. He has conducted survey, experimental, and field research at scales ranging from the global to the local, including international studies, the United States, individual states (Alaska and Florida), municipalities (New York City), and with the Inupiaq Eskimo of Northwest Alaska. He also recently conducted the first empirical assessment of worldwide public values, attitudes, and behaviors regarding global sustainability, including environmental protection, economic growth, and human development. He has served as a consultant to the John F. Kennedy School of Government (Harvard University), the United Nations Development Program, the Gallup World Poll, the Global Roundtable on Climate Change at the Earth Institute (Columbia University), and the World Economic Forum.

Jennifer Marlon

Associate Research Scientist

Jenn's research focuses on public perceptions of climate change, climate literacy, and the physical aspects of long-term environmental changes – especially wildfires. She is co-organizer of a science education and training program called the Dissertation Initiative for the Advancement of Climate Change Research (DISCCRS, pronounced “discourse”), which aims to establish connections among researchers focusing on the scientific and human dimensions of climate change. Jenn holds a PhD and MS in Geography from the University of Oregon, and a BS from the University at Albany, State University of New York.

Sander Van Der Linden

Visiting Research Associate

Sander joined the YPCCC in 2012 as a visiting research scholar to work with Dr. Anthony Leiserowitz. Sander received his PhD in social-environmental psychology from the London School of Economics and Political Science (LSE) and before coming to Yale, he was based at LSE’s Grantham Research Institute on Climate Change and the Environment. From September 2014 onwards, Sander will hold a joint appointment as a post-doctoral research fellow and lecturer in the Department of Psychology and the Woodrow Wilson School at Princeton University. Sander remains an active research associate of the YPCCC and is involved in a number of experimental research projects.  Sander’s research spans three interrelated areas: (1) judgments and perceptions of environmental risks and persuasive (risk) communication, (2) behavioral change and the psychosocial determinants of pro-environmental and pro-social behaviors and (3) psychological worldviews. Sander also maintains an active research interest in psychometrics and statistical research methods for the behavioral sciences. 


Zena Grecni

Research Assistant

Zena is a 2015 Master of Environmental Management candidate at the Yale School of Forestry and Environmental Studies.  Before entering graduate school, Zena worked at the University of Hawai‘i and the East-West Center in Honolulu, managing projects to provide state, regional, and national decision makers with actionable research and information to support their climate change adaptation initiatives. As Communications Coordinator for the Pacific Regional Integrated Sciences and Assessments (Pacific RISA) program, she developed and implemented the communications strategy for a regional climate research partnership. Here at Yale F&ES, Zena is studying climate change impacts and solutions and international environmental policy. Her assistantship at YPCCC is an opportunity to expand her communications experience, especially through harnessing the power of social media to build a community of citizen climate communicators. Ultimately, she hopes to return to Hawai‘i to facilitate collaboration in the Pacific region for sustainability and resilience. She holds a Bachelor of Arts in Environmental Studies from Oberlin College. Zena enjoys jogging in New Haven, hiking in the Appalachian Mountains, and landscape photography.

Minna Brown

Research Assistant

Hailing from Portland, OR, Minna brings a breadth of experience in online outreach and digital strategy to YPCCC.  As a Sociology/Anthropology major at Middlebury College, she translated her passion for telling effective climate change stories into internships, conferences, and her thesis on the role of climate change journalists.  Post-college, she worked as the Outreach Director for Portland-based climate advocacy group Focus the Nation, motivating diverse groups on and off campuses to get educated, engaged and active in addressing global warming in their communities.  Moving to Burlington, VT, she broadened her communication, marketing, sales, and management skills as the Client Services Manager at Union Street Media, an online marketing and design firm.  Seeking to harness those skills specifically on climate and energy issues, Minna jumped at the chance to continue her academic studies at Yale.  Now a first year Master of Environmental Management student at FES, Minna melds her interests in sustainable business and climate communication by working on digital strategy for the Center for Business and the Environment at Yale in addition and the Yale Project on Climate Change Communication.  When she's not in front of a computer screen, she's either in the kitchen whipping up something tasty, or adventuring outside.
